Science Flashcard

What is an acid?

Back

An acid is a substance that has a pH lower than 7 and can donate protons (H+) in a solution.

What is pH?

Back

pH is a scale used to measure how acidic or basic a substance is, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive peaks (or troughs) of a wave, usually measured in meters.

Front

What is frequency?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

Front

What is amplitude?

Back

Amplitude is the height of a wave from its rest position to its peak, indicating the energy of the wave.

Front

What is Newton's second law of motion?

Back

Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What happens to a smaller mass when the same force is applied as to a larger mass?

Back

The smaller mass will accelerate more quickly than the larger mass when the same force is applied.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases, and vice versa.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.
